Abstract

An optimization program was written to determine a set of channel responses for measuring object-color spectra. The program incorporated the Complex method of optimization to search the feasible space. The optimum set was determined based upon minimization of the number of channels, the average color difference (AE*ab) over a set of 116 colors and three illuminants, and the average reflectance factor difference between the actual and estimated spectra. It was expected that it would be possible to identify a system which would fall between current spectrophotometers and the ideal but unrealizable system whose responses are the three CIE standard color-matching functions weighted by the three illuminants. It was found that even with as few as six channels, each a gaussian with specific mean and bandwidth, reasonable performance could be attained.
